Remote sites (3 of them) linked to a primary site that has a fixed IP running latest Tomato.

Remote sites are running Tomato Firmware v1.27vpn3.6.4b6645f6(ND) on an Asus WL-520GU, have a dhcp WAN with cable company.

VPN Tunnel sometimes drops and must be reconnected manually using the gui. I believe it has something to do with the WAN picking up a new IP / renewing dhcp lease. I have attached 24 hours worth of logs. At the bottom, the VPN disconnected and did not reconnect. In the middle somewhere, transition went smoothly. All three sites have the same problem but usually only one or two of them per week fail.

I am getting exactly the same problem. I have been assuming it's my DSL connection (I'm at nearly the limit for distance from the central office for still having DSL service), but now I've begun wondering if it's my Tomato firmware settings.
